Why clean compressed air is crucial in pressure and 3D printing processes
Oil-free compressed air: a prerequisite for consistent product quality
High-quality compressed air is of central importance for production processes in printing works and in 3D printing. It plays a key role in determining the quality of the manufactured products. Contaminants such as oil, moisture or particles have a direct impact on surface quality and dimensional accuracy. Even the slightest contamination can lead to visible quality defects, dimensional deviations or scrap. Dry and clean air is therefore a fundamental prerequisite for consistently high-quality results – from traditional printing to industrial 3D printing.

As well as influencing the quality of the end product, compressed air plays a key role in the stability and reliability of production processes. Pneumatic systems are crucial here, performing motion, control and positioning tasks. The quality of the compressed air used has a direct impact on process stability, plant availability and the quality of the manufactured products. Contaminants such as oil, moisture or particles can cause malfunctions, increase wear and tear, or lead to visible quality defects. For this reason, clean, dry compressed air is essential in printing and 3D printing applications. Consistent compressed air conditions support reproducible processes, reduce unplanned downtime and contribute to high plant availability. Clean, dry air protects sensitive components and pneumatic systems in printing and manufacturing plants from wear and malfunctions. Our oil-free compressors reliably deliver oil-free compressed air and operate without an internal oil source. In combination with diaphragm dryers, they produce consistently dry and clean air for demanding applications in printing and 3D printing. You can flexibly determine the required level of purity depending on the application and the filter system used – tailored to the material, process and quality requirements. This is because, particularly in automated printing and 3D printing processes, a defined compressed air quality is a key factor for efficient, safe operation.
Typical applications of compressed air for printing presses and 3D printers
Oil-free compressors support a wide range of applications in industrial manufacturing:
Printing works
by powering the pneumatic components within the system and ensuring reliable operation. The compressed air supply is therefore an integral part of the machine design. A typical example is the air spindle, a pneumatic mandrel used to securely hold, centre and secure roll stock. When compressed air is supplied, a rubber tube or lamellar element inside expands, securing the roll and keeping it centred. When the compressed air is released, the spindle unloads, enabling a quick roll change. Furthermore, compressed air is used in conventional applications for material transport, ink and media handling, cleaning processes, as well as for control and regulation tasks.3D printing and additive manufacturing
Plastics and polymer 3D printing
In plastics and polymer 3D printing such as FFF, FDM, SLA or SLS (plastics), compressed air is predominantly used in 3D printing machines. Typical applications include the cooling of parts and components, the operation of actuators, peripheral devices and handling systems, as well as supporting functions within the machine environment. A stable and clean compressed air supply provided by a Dürr Technik compressor plays a key role in ensuring reproducible processes, consistent component quality and reliable plant operation.Metal 3D printing
In metal 3D printing, for example in processes such as SLM, DMLS or EBM, nitrogen is used as an inert gas. It is used to purge the printer’s process chamber and keep it inert during the printing process. This displaces oxygen and prevents the components from oxidising. The nitrogen required for this process is often generated on-site by a nitrogen generator, which in turn is powered by compressed air. A reliable, clean supply of compressed air is the basis for a stable inerting process. If a nitrogen generator without its own compressed air supply is already in use, the required compressed air can be supplied by an external, oil-free compressor from Dürr Technik. This allows existing systems to be supplemented or expanded in a targeted manner without having to redesign the entire system. Alternatively, Dürr Technik offers nitrogen generators with an integrated compressor as a complete solution.Compressor solutions for demanding compressed air and 3D printing applications
Oil-free compressors are the right choice when durable, low-maintenance systems are required for demanding industrial applications. Whether you need a single compressor or complete compressed air systems, oil-free compressed air compressors from Dürr Technik provide a reliable foundation for meeting high quality standards in printing and 3D printing.
